Abstract
A simple technique for double-contrast esophagography is described. The technique involves successive swallows of an excellent coating barium mixture and water to create the double contrast effect. Clinical and radiologic situations in which double-contrast esophagography have proven helpful include: (a) the detection of small esophageal tumors; (b) delineation of the morphologic features of neoplastic and inflammatory disease; and (c) assessment of the total vertical extent of esophageal disease. Accurate and/or confident diagnosis is aided considerably with double-contrast esophagography.
